Privacy preserving electronic document signature service

Abstract

An electronic document signature system preserves the security of an electronic document while tracking a signature process corresponding to the electronic document. In particular, using a client application on a client device, an originating user can protect an electronic document and send the protected electronic document to a tracking server. The tracking server receives only a protected document such that the security the electronic document is preserved. Using a client applications on client devices, one or more participating users can subsequently receive the protected document from the tracking server, access the contents of the electronic document, and sign the electronic document. The tracking server can record events that occur with respect to the protected document to create an event log.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]N / A.BACKGROUND[0002]1. Technical Field[0003]The present disclosure relates generally to providing an electronic document signature service. More specifically, one or more embodiments relate to systems and methods of securely tracking and verifying user signatures with respect to an electronic document.[0004]2. Background and Relevant Art[0005]Creating, sharing, and storing electronic documents is a common part of modern life. In many instances, business or individual users have the need to share an electronic document for purposes of obtaining various signatures. For example, users may desire to track an electronic signature (or “e-signature”) process for an electronic document as multiple users sign the electronic document.[0006]As is often the case, the various users that may need to sign a particular electronic document are geographically located throughout the world and / or are associated with different organizations. Therefore, some c...

AI Technical Summary

Benefits of technology

The patent text describes a system and method for maintaining the security of electronic documents within an electronic document signature system. The system allows users to sign documents without storing a version of the document within the system. The system can track and verify the signature of a document, while preserving its security. This allows users to send protected documents to a tracking server without compromising their content. The tracking server can also create a log of document events, providing verification without accessing the document contents. The technical effect of this system is that it allows for efficient and safe use of electronic signatures, maintaining the privacy of sensitive information. It also reduces the liability risk for the service provider.

Problems solved by technology

The sensitive or confidential information creates issues for the users of the document signature service, as well as the providers of the document signature service.

In the first instance, most users are hesitant to send sensitive or confidential information to a third-party service.

Regardless of the sophistication and reputation of the third-party provider, the third-party provider in conventional electronic document signature services has access to the sensitive or confidential information, which creates an inherent risk.

For example, a data security breach in the document signature service could result in compromising the document contents.

In many situations the risk of compromising the sensitive or confidential information outweighs the benefits of using the document signature system.

From a document signature service provider's perspective, there are a number of additional problems associated with storing electronic documents that contain sensitive or confidential information.

For example, in the event that a security breach occurs within the document signature service, the provider may be liable for damages that result from the compromised sensitive and confidential information.

Depending on the type of confidential information compromised, the provider's liability could be substantial.

In addition, any compromise in sensitive and confidential information would severely diminish the brand of the provider, substantially damaging the provider's own business.

The security systems and features not only involve significant resources, but they often further complicate the operation of conventional document signature services.

Moreover, even with the best security systems, features and procedures, a provider may never completely eliminate the risks associated with storing confidential information associated with a conventional document signature service.

In addition to the liability and expense associated with trying to protect confidential information, the providers of conventional electronic document signature services often deal with subpoenas and other requests to obtain electronic documents stored in the system.

The time and resources needed to respond properly to subpoenas and other requests for information may create a large operational burden for the provider.

Therefore, the mere fact that conventional document signature service providers have access to the contents of the documents may create a significant expense and burden.

These and other disadvantages may exist with respect to conventional electronic signature services.
